Never heard of the brand "Rx" but they appear to be good. SS, 3/8" flange, those are the big ticket items. I'd recommend not using the supplied gaskets and getting quality ones, though. Possibly the hardware too.

they rock for the price. +1 on grade 5 hardware (supplied is super soft and I had to drill out a broken one on account of it), and be sure to test fit your gasket against the spark plug heat shields. they hit on mine and needed trimmed.
